Title: Process for painting snow
Inventor: ADAMS THEODORE P
IPC: B44D2/00
Filed: 1992-02-28
Abstract: PROCESS FOR PAINTING SNOW                   ABSTRACT OF THE DISCLOSURE    A process of allowing one to paint or draw on snow whereby a coloring agent,  such as food coloring,  is mixed with a gelling agent, such as household gelatin, and applied with a spray or squirt gun.  When the gel solution  contacts  the  cold  snow,  the  gel  solution quickly sets up and is prevented from dissipating as snow undergoes partial melting.   When snow melts, the gel liquifies and disappears with runoff water.
Patent CA-2064064-A1 (CA)
Inventor: HEHNER REINHARD
IPC: B65H23/195
Filed: 1991-02-01
Abstract: In prior art processes for winding continuous webs of material (1), in particular paper or carton, on to spools, the material (1) pulled off a delivery roll against a braking force is divided, by cutting it along its length, into individual strips which are subsequently wound under tension onto individual rolls (19, 20). In order to be able to set different tensions for cutting and for winding at the winding stations (9, 10), the invention calls for the tension of the individual strips after cutting and before winding to be interrupted by passing the strips over a driven roller with which the strips lock fractionally. The tension is preferably interrupted by a free-running roll (22) which presses against the driven roller, thus holding the individual strips in place.

Abstract: Méthode et appareil d'enregistrement d'information d'un support principal sur un support secondaire. Dans une version, une information numérique contenue sur un support maître est reproduite et stockée à une première vitesse, généralement en temps réel, dans un premier dispositif de stockage numérique à grande vitesse, p. ex. une unité de disque magnétique. Cette information numérique stockée dans le premier dispositif de stockage est au besoin transférée, à une deuxième vitesse beaucoup plus rapide que la première, vers un deuxième dispositif de stockage numérique dans lequel elle est stockée jusqu'au moment prévu pour sa reproduction. Elle est alors lue à plusieurs reprises à une troisième vitesse, beaucoup plus rapide que la première et plus lente que la deuxième, puis convertie sous forme analogique et appliquée à un dispositif de reproduction pour l'enregistrement de l'information analogique sur un support asservi. Comme l'information stockée dans le premier dispositif de stockage numérique ne sert pas directement à la production, le dispositif de reproduction peut reproduire de l'information auparavant transférée du premier dispositif de stockage au deuxième en même temps que l'information est reproduite à partir d'un support maître et chargée, en temps réel, dans le premier dispositif de stockage.

Inventor: OHTA KENJI
IPC: G11B11/10
Filed: 1992-10-22
Abstract: A magneto-optical memory device is provided with a recording track having a recording film and a guide track.  In the guide track is formed a perpendicular magnetic film, whose magnetization direction is arranged in one direction.   The recording track and the guide track are alternately disposed. A recording operation is carried out, using a circular magnetic field  generated  by  the  perpendicular  magnetic  film,  by projecting a light beam only on the recording track so as to raise the temperature of the recording film.  When erasing, the light beam is projected on the recording track and respective portions of the guide tracks located on both sides of the recording track so as raise the temperature thereof.  As the temperature  rises,  the magnetization  of  the  perpendicular magnetic film is reduced, and an erasing operation is then performed using an external magnetic field.

Title: Substrate for optical recording medium and magneto-optical recording medium using same
Inventor: SEKIYA MASAHIKO
IPC: G11B7/243
Filed: 1992-11-26
Abstract: The reproduction characteristics, particularly the C/N ratio of a reproduced signal of an optical recording medium are deteriorated by an unevenness or deformation of an optical recording layer due to a convex or concave configuration of an underlying guide means is formed on the surface of the substrate. This deterioration can be prevented by disposing a planalization layer under the recording layer but the planalization layer lowers the efficiency of the servo tracking.  This lowering of servo tracking efficiency is prevented by insertion of a dielectric layer between the planalization layer and the guides.

Title: Optical apparatus and method for displaying the image of a large field which is situated in an inadequate position to be direct watched
Inventor: DAVID ION
IPC: B60R1/08
Filed: 1993-09-13
Abstract: ABSTRACT OF THE DISCLOSURE            Optical apparatus and method for displaying in an aggregate forme of  the image of a field which is situated in an inadequate position to be direct watched, for example the  field image behind the back of the motor vehicle, image which is collected under a large angle (as far as 180°) and it is transmitted into the visual field of the observer (the driver), are disclosed.The construction of the apparatus comes into being through combinations of;mirrors, prisms, refracting medium, glass plates, lenses and fibre optics. The apparatus is composed of three sections:field image-collecting member (the objective), image-transmitting member(the extender), and image-receiving and displaying member(the display). Thus, the field image behind the back of the motor vehicle is collected and processed ( i.e. it is  made smaller, is made stable, and the aberrations are corrected, depending on the complexity of the apparatus ) by the objective which is connected to one end of the image-transmitting member (extender). The image obtained in this way through objective is transmitted by the image-transmitting member (extender) to the image-receiving and displaying member (display) which is connected on the other end of the image-transmitting member (extender). The image-receiving and displaying member (display) receives the image, it processes it again ( i.e. the image is made larger if it is received below the needed dimensions of displaying, it is erected and/or reverted if it is received in an inverted and/or reverted position as compared to the field image of interest, and the aberrations are corrected if necessary ), and it displays the image into the visual field of the driver. Any member of the apparatus  (objective, extender and display) can be placed anywhere and in any position. The image does not become deformed, adjustments are not necessary to receive a stable image, and the negative effects of the impurities fallen on the surface through which the objective collects the image are diminished. The apparatus increases the confort and security in motor  vehicle  driving  process  getting  the  possibility  of  a simultaneous control for both fields, it can be adapted at any sort of motor vehicle, and offers resources of modern design. The field image behind the back of motor vehicle can be obtained completely, without uncovered angles, this quality being necessary more particulary for big trucks. Through its proprieties, the new apparatus also offers a better security for vehicles destined to special transports (banks, police, etc.) .
Patent CA-2109602-A1 (CA)
Inventor: WINTER GREGORY P
IPC: G01N33/53
Filed: 1992-05-15
Abstract: The invention provides methods and kits for producing specific binding pairs (sbp) members. Populations of polypeptide chain components of sbp members are combined to form libraries of sbps displayed by secreted replicable genetic display pack-ages (rgdp). At least one of the polypeptide chains is expressed as a fusion with a component of an rgdp which thereby displays that polypeptide chain at the surface of rgdp. At least one population of polypeptide chains is expressed from nucleic acid which is capable of being packaged using a component of an rgdp, whereby the genetic material of rgdps produced encodes a polypep-tide chain. The methods enable production of libraries of multimeric sbp members from a very large number of possible combina-tions. In one embodiment of the invention a method emplays "chain shuffling"  in the production of sbp members of desired spe-cificity for a counterpart sbp member. Selection procedures are also described.
